FAULT CIRCUIT INTERRUPTERS (GFCI)
The entrance to a room that contains exposed
live electrical parts must be posted with a conspicuous sign indicating restricted
entry. (Industrial Establishments Regulation 851/90, 41)
The power supply must be locked out before work near live exposed parts. The worker must ensure that the power is locked out. Lockout is not required if the conductors are grounded or less than 300 volts, and there is no locking device for breakers or fuses.
There must be a written procedure for electrical work.
If there is more than one worker, the worker that locked out
must communicate the lock out to others. A tag may be used for communication
purposes. (Industrial Establishments
Regulation 851/90, 42.1)
If it is not practical to disconnect the power before working near live exposed parts, the worker must use rubber gloves, mats, or shields as protective equipment to protect against shock and burns. If the voltage is greater than 300 volts and live work is to be performed, a competent person must stand by to perform rescue. (Industrial Establishments Regulation 851/90, 43)
Conducting
tools and equipment must not be used close to live electrical work.
